Four
1) Inactivated/Toxoids
2) Conjugated
3) Live Attenuated
4) Inactivated/Killed
What are Inactivated/toxoid vaccines?
Includes the “parts” that best stimulate immune response?
What are examples of inactivated/toxoid vaccines?
Tetanus, diphtheria
What are conjugated vaccines?
- Pathogens are surrounded by a polysaccharide capsule
- Immunogenic: Will trigger immune response (T-cell dependent)
- Immune Response strengthened when pathogen is conjugated with carrier protein?
What are examples of conjugated vaccines?
- Meningococcal
- Pneumococcal
- Haemophilus Influenzae B
- Hepatitis B
- Influenza (injection)
- HPV
- Pertussis (whooping cough)

- Stronger mucosal immunity develops
- Not for those who are immunocompromised

- MMR (measles, mumps, rubella)

- Influenza (nasal spray)
- Zoster (shingles) for adult

When should you get meningococcal vaccines?
